FBI identify Michigan Mormon church shooter, investigations ongoing

The FBI is unleashing all the investigators they can to try and narrow down a motive tied to the mass shooting at a Mormon church in Michigan.

At least 100 federal investigators are looking into it and so far have determined that a former marine crashed a pickup into the church, shot into the building and then set it ablaze during a Sunday service.

Authorities say at least four people have been killed, and roughly 8 people were hurt.

As of Monday, search crews in Michigan say they did not find any additional bodies in the rubble, and are certain everyone was accounted for.

Despite not having a clear motive, authorities have identified the shooter as Thomas Jacob Sanford, an Iraq war veteran.
